Efficacy of interferon alpha in the treatment of refractory and sight threatening uveitis: a retrospective monocentric study of 45 patients.

AIM: Severe uveitis is potentially associated with visual impairment or blindness in young patients. Therapeutic strategies remain controversial. The efficacy of interferon alpha-2a (IFN-alpha2a) in severe uveitis, refractory to steroids and conventional immunosuppressive agents, was evaluated. PATIENTS AND METHODS: Patients were included after a major relapse of uveitis following corticosteroids and immunosuppressants. IFN-alpha2a (3 million units three times a week) was administered subcutaneously. Efficacy was assessed by improvement in visual acuity, decrease in vitreous haze, resolution of retinal vasculitis and macular oedema, assessed by fundus examination and fluorescein angiography, and decrease in oral prednisone threshold. RESULTS: 45 patients were included. Median age was 32.3 years (range 8-58) and sex ratio (F/M) was 0.66. Uveitis was associated with Behçet's disease in 23 cases (51.1%) and with other entities in 22 cases (48.9%). Median duration of uveitis before interferon therapy was 34.9 months (range 3.4-168.7) and an average of 3.26 relapses following corticosteroids and immunosuppressants was noted. Uveitis was controlled in 82.6% of patients with Behçet's disease and 59% of patients with other types of uveitis (p = 0.07). During a mean follow-up of 29.6 months (range 14-55), median oral prednisone threshold decreased significantly from 23.6 mg/day (range 16-45) to 10 mg/d (range 4-14) (p<0.001). Interferon was discontinued in 10 patients (22.2%) with Behçet's disease and in four patients without Behçet's disease. Relapses occurred in four and one cases, respectively. CONCLUSIONS: Interferon therapy appears to be an efficient strategy in severe and relapsing forms of Behçet's disease but also in other uveitic entities. However, it seems to act more to suspend rather than cure the disease. Therefore, IFN-alpha2a may be proposed as a secondline strategy after failure of conventional immunosuppressants.

Cardiomyopathy related to antimalarial therapy with illustrative case report.

The antimalarial agents, chloroquine (CQ) and hydroxychloroquine (HCQ) are used in long-term treatment of connective tissue diseases and dermatological disorders and are generally regarded as safe. We present one case of cardiotoxicity in a 59-year-old woman treated with antimalarials during 13 years for a discoid lupus erythematosus. She progressively developed conduction disturbances and congestive heart failure (CHF). When the diagnosis of antimalarials toxicity was suspected, CQ was withdrawn. However, heart transplantation had to be performed in the following 4 months for severe CHF. Indeed, rare but severe cardiotoxicity may develop following prolonged use of antimalarials with both conduction disturbances (45 patients) and CHF (25 patients). These cardiac toxic effects have been reported with CQ and less frequently with HCQ use alone. Diagnoses are often delayed since the toxicity of the drug might be misattributed to other factors in these patients. The endomyocardial biopsy, or in some cases the muscle biopsy, are essential to confirm the antimalarials toxicity. Antimalarials have been stopped in 12 cases of CHF, leading to improvement in 8 cases (within 3 months to 5 years) and to deaths or to heart transplantation in 4 cases (within 1 week to 3 months). In the latter cases, as in our patient, the lack of improvement may have been explained by the severity of the cardiomyopathy at diagnosis and the short delay since withdrawal. As a consequence, the potential for reversibility and the severity in undiagnosed cases of these toxic cardiomyopathies emphasize the importance of recognizing early signs of toxicity in order to withdraw antimalarials before the occurrence of life-threatening CHF.

Pulmonary arterial hypertension is a major mortality factor in diffuse systemic sclerosis, independent of interstitial lung disease.

OBJECTIVE: To determine whether pulmonary arterial hypertension (PAH) is a prognostic factor for mortality in diffuse cutaneous systemic sclerosis (dcSSc), independent of interstitial lung disease (ILD). METHODS: ILD was diagnosed by high-resolution computed tomography and PAH (pulmonary arterial systolic pressure [PASP] > or =45 mm Hg) by echocardiography. All patients with ILD underwent testing for total lung capacity (TLC), forced vital capacity (FVC), and diffusing capacity for carbon monoxide. RESULTS: Eighty-six patients with dcSSc (mean age at diagnosis 44.5 years) were followed up for a median of 72.5 months. ILD was found in 52 patients (60%) and PAH in 18 (21%). ILD was associated with PAH in 15 patients. Seventeen patients died (19.8%), 9 of whom had PAH (P = 0.001) and 10 of whom had ILD (P = 0.99). By multivariate analysis, age at SSc diagnosis and PAH were the only independent predictors of death (hazard ratio [HR] 1.057, 95% confidence interval [95% CI] 1.009-1.109, P = 0.020 and HR 4.09, 95% CI 1.47-11.5, P = 0.007, respectively). Mean TLC and mean FVC were similar in ILD patients with and those without PAH (P = 0.71 and P = 0.40, respectively). Among ILD patients, age at SSc diagnosis and PAH were again the sole predictors of death (HR 1.073, 95% CI 1.003-1.149, P = 0.042 and HR 5.07, 95% CI 1.09-23.8, P = 0.038, respectively). Twenty ILD patients received at least 6 monthly pulses of intravenous cyclophosphamide (CYC). In CYC-treated patients with PAH (n = 8), PASP increased significantly during the CYC regimen (mean +/- SD 55 +/- 14.5 mm Hg; P = 0.015 versus baseline), while TLC remained stable during the same period. CONCLUSION: These results indicate that, independent of ILD, PAH is a major prognostic factor for survival in dcSSc.

Low blood concentration of hydroxychloroquine is a marker for and predictor of disease exacerbations in patients with systemic lupus erythematosus.

OBJECTIVE: To study the possible relationship between whole-blood hydroxychloroquine (HCQ) concentrations and clinical efficacy of HCQ in patients with systemic lupus erythematosus (SLE). METHODS: Whole-blood HCQ concentrations were measured, under blinded conditions, in 143 unselected patients with SLE who had been receiving HCQ 400 mg daily for at least 6 months. The relationship of these concentrations to current disease activity and to subsequent exacerbations during 6 months of followup was investigated. RESULTS: At baseline, 23 patients had active disease (mean +/- SD SLE Disease Activity Index 12.4 +/- 7.5). The mean whole-blood HCQ concentration in this group was significantly lower than that in the 120 patients with inactive disease (694 +/- 448 ng/ml versus 1,079 +/- 526 ng/ml; P = 0.001). Among the 120 patients who had inactive disease at baseline, the mean HCQ concentration at baseline in the 14 (12%) who had disease exacerbations during followup was significantly lower than that in the patients whose disease remained inactive. Multivariate logistic regression showed that the HCQ concentration was the only predictor of exacerbation (odds ratio 0.4 [95% confidence interval 0.18-0.85], P = 0.01). Receiver operating characteristic curve analysis showed that a whole-blood HCQ concentration cutoff of 1,000 ng/ml had a negative predictive value of 96% for exacerbation during followup. CONCLUSION: Low whole-blood HCQ concentrations are associated with SLE disease activity and are a strong predictor of disease exacerbation. Regular drug assaying and individual tailoring of treatment might help to improve the efficacy of HCQ treatment in patients with SLE.

Variability in the efficacy of interferon-alpha in Erdheim-Chester disease by patient and site of involvement: results in eight patients.

OBJECTIVE: Erdheim-Chester disease (ECD) is a rare, non-Langerhans form of histiocytosis of unknown origin, characterized by infiltration of tissues by spumous histiocytes. ECD features heterogeneous systemic manifestations, and the general prognosis remains poor despite various treatment options. METHODS: We treated 8 patients with multisystemic ECD with subcutaneous interferon-alpha (IFNalpha) at a dosage of 3-9 x 10(6) units 3 times weekly, for a median duration of 23 months (range 1-46 months). RESULTS: Treatment was generally well tolerated, and side effects remained limited to fever following injections. Treatment was discontinued in 1 patient, because of severe depression. During treatment, some manifestations of ECD disappeared (i.e., xanthelasma, exophthalmos, papilledema, and intracranial hypertension). The efficacy of IFNalpha on cardiovascular ECD was variable, however. Treatment resulted in partial regression of "coated aorta" in some cases and clear failure in others; 2 patients died. The level of C-reactive protein diminished sharply in 5 patients. CONCLUSION: IFNalpha might be a valuable first-line therapy for prolonged treatment of ECD. However, the efficacy of IFNalpha varies among patients and according to the sites of disease involvement, and symptoms may fail to respond to treatment, especially in patients with severe multisystemic forms of ECD with central nervous system and cardiovascular involvement.

High-dose chemotherapy followed by autologous hematopoietic stem cell transplantation for adult histiocytic disorders with central nervous system involvement.

We postulated that high-dose chemotherapy (HDC) followed by peripheral autologous hematopoietic stem cell transplantation might help to control refractory central nervous system (CNS) histiocytic disorders. Six patients with histiocytic CNS involvement were treated in this way. Two patients achieved non-active disease status, although one relapsed at 84 months. Two patients had regressive disease, one of whom progressed at 21 months. One patient had progressive disease at 14 months. One patient had extra-CNS progression but CNS regression. After a median follow-up of 22.4 months, only one of the six patients still has non-active disease. Treatment was effective on craniofacial and space-occupying brainstem lesions, and was ineffective on neurodegenerative lesions.

Bone involvement in Erdheim-Chester disease: imaging findings including periostitis and partial epiphyseal involvement.

PURPOSE: To retrospectively review the bone findings at radiography, scintigraphy, computed tomography (CT), and magnetic resonance (MR) imaging in 11 patients with immunohistochemical and histologic proof of Erdheim-Chester disease. MATERIALS AND METHODS: This study was designed as a retrospective review; approval of the institutional review board and patient consent were not required for this type of study. Eleven patients (eight men and three women; mean age, 49 years; range, 17-68 years) with Erdheim-Chester disease underwent conventional radiography of the skeleton and bone scintigraphy. Two patients underwent CT of the femora and 10 underwent CT of the skull. Eight patients underwent MR imaging. Conventional radiographs, bone scintigrams, CT scans, and MR images were reviewed in consensus by four musculoskeletal radiologists. RESULTS: All 11 patients had involvement of the long bones and normal axial skeleton, hands, and feet. Bilateral and symmetric osteosclerosis of the diaphysis of the long bones was present in 52 (26 pairs) (98%) of the 53 bone lesions visible on conventional radiographs. Osteosclerosis was heterogeneous in 65% of the patients and homogeneous in 35%. Diaphysis was involved in 100% and metaphysis in 44 (83%) lesions. Partial epiphyseal involvement sparing the subchondral bone was present in 24 (45%) lesions. Periostitis was seen in 35 (66%) and endosteitis in 50 (94%) of the 53 long bones involved. Bone scintigraphy depicted tracer uptake in all bone lesions visible on radiographs. Skull and face bone lesions were present in two patients. MR imaging depicted a replacement of the normal fatty bone marrow by heterogeneous signal intensity on T1- and T2-weighted spin-echo images. Lesion extent, epiphyseal involvement, and periostitis were clearly depicted at MR imaging. CONCLUSION: This series provides a detailed description of bone involvement in Erdheim-Chester disease. Periostitis and partial epiphyseal involvement of the long bones are also features of this disease. (c) RSNA, 2005.

[Behçet's disease].

Behçet's disease is a vasculitis of unknown origine. Mucocutaneous manifestations are necessary for diagnosis. Ocular and neurological involvements can lead to severe impairment. Arterial involvement may be lethal. Treatment is only symptomatic using steroids, colchicine and antiaggregant therapy. Immunosuppressive drugs are generally given for severe manifestations resistant to conventional therapy. Alpha interferon and infliximab are interesting in case of failure or relapses despite treatment. As in all chronic diseases, education and good observance are needed to improve prognosis.

Association of the R92Q TNFRSF1A mutation and extracranial deep vein thrombosis in patients with Behçet's disease.

OBJECTIVE: Behçet's disease is a chronic, relapsing, multisystemic inflammatory disorder characterized by recurrent oral and genital ulcers and by ocular, articular, vascular, and central nervous system involvement. The tumor necrosis factor alpha (TNFalpha) pathway is likely involved in the pathophysiology of Behçet's disease. One of the 2 TNFalpha receptors is TNF receptor superfamily 1A (TNFRSF1A). We searched for R92Q TNFRSF1A mutations in patients with Behçet's disease. METHODS: A search for TNFRSF1A mutations was performed by polymerase chain reaction amplification of the TNFRSF1A gene, followed by denaturing high-performance liquid chromatography scanning. RESULTS: Among the 74 unrelated European patients with Behçet's disease, 5 (6.8%) carried the R92Q TNFRSF1A mutation. The frequency of the R92Q mutation in patients with Behçet's disease was significantly higher than that in controls (P = 0.006 by Fisher's exact test). Deep vein thrombosis was significantly associated with the R92Q mutation (P = 0.001 [with Bonferroni adjustment for multiple comparisons]). Among the 30 patients with thrombosis, 10 had cerebral thrombophlebitis. None of these patients had the R92Q mutation. Among the 20 patients with Behçet's disease who had extracranial deep vein thrombosis, 6 had the R92Q mutation, whereas 14 did not (P < 0.0001) CONCLUSION: The R92Q mutation in patients with Behçet's disease is associated with an increased risk of extracranial venous thrombosis. This new finding may help in understanding the complex prothrombotic state in patients with Behçet's disease.

Efficacy of interferon-alpha for the treatment of Kaposi's sarcoma herpesvirus-associated uveitis.

PURPOSE: To report cases of uveitis that are associated with human herpesvirus-8 (HHV-8) and the impact of interferon-alpha therapy on their visual outcome. DESIGN: Interventional case reports. METHODS: Extensive examination was performed in patients with chronic and severe uveitis to exclude a viral cause that requires specific therapy. After histopathologic, molecular, and/or serologic confirmation of HHV-8 uveitis, interferon-alpha2a therapy (3 millions IU/d, 3 days per week, subcutaneously) was initiated. RESULTS: Two patients of Mediterranean origin were included. HHV-8 serologic result was positive in both cases. Histopathologic examination of conjunctival biopsy specimens confirmed Kaposi's sarcoma in the second case, and quantitative polymerase chain reaction identified HHV-8 DNA in the biopsy specimen. Disease was controlled by interferon-alpha2a in both cases, but maintenance therapy was mandatory to prevent relapses. CONCLUSION: HHV-8-associated uveitis is a rare condition in immunocompetent hosts. Severe and chronic conditions may require antiviral and immunomodulatory therapies. Interferon alpha seems to be a good candidate and may be proposed in these cases.

Tumor antigen markers for the detection of solid cancers in inflammatory myopathies.

Dermatomyositis and polymyositis patients have an increased risk of developing cancers. We have assessed the diagnostic values of serum tumor markers for the detection of solid cancer in dermatomyositis/polymyositis patients. Serum carcinoembryonic antigen, CA15-3, CA19-9, and CA125 were assayed by immunoradiometric methods in 102 dermatomyositis/polymyositis patients. All the patients had complete physical examination, chest X-ray, echocardiogram, gastrointestinal tract endoscopic explorations, thoracoabdomino-pelvic computed tomography scan, and all women had gynecologic examination and mammogram. Exclusion criteria for study were childhood dermatomyositis, inclusion body myositis, myositis associated with a connective tissue disease, prior history of cancer, and the presence of benign conditions known to elevate serum tumor markers. After a median follow-up of 59 months, 10 (9.8%) patients had a solid cancer. Initial elevation of CA125 was associated with an increased risk of developing solid cancer [P = 0.0001 by Fisher's exact test; odds ratio (OR), 29.7; 95% confidence interval (95% CI), 8.2-106.6]. For CA19-9, there was a trend towards a significant association (P = 00.7; OR, 4.5; 95% CI, 1-18.7, respectively). Diagnostic values of elevated CA125 and CA19-9 at screening increased when the study analysis was restricted to patients who developed a cancer within 1 year (P < 0.0001 and P = 0.018, respectively) or to patients without interstitial lung disease (P = 0.00001; OR, 133; 95% CI, 6.5-2733 and P = 0.027; OR, 9; 95% CI, 1.5-53, respectively). Individual comparisons of the baseline and the second CA125 value showed that three of the eight patients with cancers versus 3 of the 76 patients without, displayed an increase of their CA125 level (P = 0.01 by Fisher's exact test). We conclude that CA125 and CA19-9 assessment could be useful markers of the risk of developing tumors for patients with dermatomyositis and polymyositis and should therefore be included in the search for cancer in dermatomyositis/polymyositis patients, especially for patients without interstitial lung disease.

Hemochromatosis and femoral head aseptic osteonecrosis: a nonfortuitous association?

Chondrocalcinosis, chronic pseudo-osteoarthritis arthropathy, and osteoporosis are classic osteoarticular complications of hemochromatosis (HC). Within HC, femoral head aseptic osteonecrosis (FHAO) is not notified in textbooks. We describe 3 cases of FHAO occurring in this setting in 3 patients homozygous for the C282Y mutation on HFE gene who had no other risk factors for FHAO. FHAO was diagnosed 9 years before (Case 1), concomitantly with (Case 3), or 9 years after HC (Case 2). In one case, FHAO occurred although phlebotomies were regularly carried out. There are scarce data available in the literature on HC and FHAO. Our observations suggest FHAO may be an indicator for HC, and iron balance should be determined before considering FHAO as idiopathic. Thus phlebotomy may not be protective against the occurrence of FHAO. Studies are needed to determine the prevalence of HC in consecutive patients with FHAO.

Outcome of pregnancies in patients with anti-SSA/Ro antibodies: a study of 165 pregnancies, with special focus on electrocardiographic variations in the children and comparison with a control group.

OBJECTIVE: Aside from congenital heart block (CHB), sinus bradycardia and prolongation of the corrected QT (QTc) interval have been reported in infants born to mothers with anti-SSA antibodies. To assess the pathologic nature of these manifestations, this study focused on electrocardiographic (EKG) variations in these children, comparing them with findings in a control group. METHODS: We studied 165 consecutive pregnancies in 106 anti-SSA-positive women with connective tissue diseases (CTDs). EKGs obtained on 58 children of this group were compared with those obtained on 85 infants born to mothers with CTD who were negative for both anti-SSA and anti-SSB. RESULTS: No statistically significant difference was seen between the 2 study groups with regard to gestational age, prematurity, birth weight, age of the children at the time of EKG, age of the mothers, or treatments received by the mothers during their pregnancies. Seven of 137 children developed cutaneous neonatal lupus syndrome; 1 child developed CHB (CHB risk of 1 in 99 [1%] if only the first prospectively observed pregnancy in women without a history of CHB is included in the analysis). For EKGs recorded during the first 2 months of life, the mean +/- SD PR interval was 96 +/- 16 msec in the anti-SSA-positive group and 96 +/- 13 msec in the anti-SSA-negative group (P = 0.84), with mean QTc values of 397 +/- 27 and 395 +/- 25 msec (P = 0.57) and mean heart rates of 141 +/- 23 and 137 +/- 21 beats per minute (P = 0.20), respectively. No difference in the PR interval, QTc interval, or heart rate was observed for EKGs obtained between 2 and 4 months of life. When EKGs obtained at 0-2 months were compared with those obtained at 2-4 months, a physiologic prolongation of the QTc interval was observed in both study groups. No sudden infant death or symptomatic arrhythmia occurred during the first year of life. CONCLUSION: The EKG findings in children of anti-SSA-positive and anti-SSA-negative mothers were not significantly different. Our results suggest that the prolongation of the QTc interval and sinus bradycardia that have recently been reported in children of mothers with anti-SSA antibodies occur independently of the anti-SSA antibodies. The pathologic nature of these EKG variations was not confirmed by our controlled study.

Cardiac sarcoidosis: a retrospective study of 41 cases.

This retrospective study concerned 18 female and 23 male patients with cardiac sarcoidosis (CS). The average age at CS diagnosis was 38 years. CS was observed in white (73% of cases) and in black or Caribbean patients (27% of cases). All patients had extracardiac histologic proof of sarcoid tissue. In 63% of cases, the CS arose during the follow-up of systemic sarcoidosis. Systemic sarcoidosis was not specific except for a high frequency of neurosarcoidosis. Revealing cardiac signs were clinical in 63% of cases and electrical in 22%. In most patients these signs were associated with an abnormal echocardiography (77%) and/or a defect on thallium-201 or sestamibi imaging (75%). Thirty-nine patients received steroid therapy (initial dose mostly equal to 1 mg/kg per day), associated in 13 cases with another immunosuppressive treatment. In 26% of cases the immunosuppressive treatment was associated with a specific cardiac treatment. In the long-term follow-up (average follow-up, 58 mo), 87% of the cases showed an improvement, and 54% were cured from a clinical and laboratory point of view (electrocardiogram, 24-hour monitoring, echocardiography, radionuclide imaging). There was no sudden death. Two patients worsened, which can be explained in 1 case by very late treatment and in the other case by lack of treatment, except for a pacemaker. Our experience leads us to treat CS with corticosteroids as soon as possible and to use another immunosuppressive treatment where there is an insufficient therapeutic response or where there are contraindications to corticosteroids.

Cardiovascular involvement, an overlooked feature of Erdheim-Chester disease: report of 6 new cases and a literature review.

Erdheim-Chester disease (ECD) is a rare, non-Langerhans form of histiocytosis of unknown origin. It is characterized by xanthomatous or xanthogranulomatous infiltration of tissues by spumous ("foamy") histiocytes. As of this writing, 178 cases have been reported. ECD is characterized by heterogeneous systemic manifestations. Bone pain is the most frequent symptom. About half of all patients have extraskeletal manifestations. Cardiovascular manifestations of ECD remain underestimated. We report 6 new cases of ECD associated with periaortic fibrosis. In 4 of these cases, the whole aorta had a "coated" aspect. A literature review revealed 66 cases of ECD with cardiovascular involvement. We therefore analyzed 72 ECD patients with cardiovascular involvement: 40 (55.6%) had periaortic "fibrosis," 32 (44.4%) had pericardial involvement, and 22 (30.6%) had myocardial involvement. Six had a right atrial tumor. Symptomatic valvular heart disease (3 aortic and 3 mitral regurgitations) was found in 6 patients. Nineteen patients (26.4%) had heart failure, leading to death in 8 cases. Six patients had renovascular hypertension related to perirenal artery stenosis. Data concerning follow-up were available for 58 (80.6%) patients. Of these, 35 (60.3%) patients died, confirming the severe prognosis of ECD. Cardiovascular complications were responsible for the death of 11 of the 35 patients (31.4%).

Late-onset systemic lupus erythematosus: a personal series of 47 patients and pooled analysis of 714 cases in the literature.

Systemic lupus erythematosus (SLE) is uncommon after the age of 50 years, and studies of elderly patients with SLE are scarce. We conducted the current study to analyze characteristics and outcome of patients with late-onset SLE in a French tertiary referral center, and to compare them with those of younger patients with SLE. From 1980 to 2000, 47 patients were identified as having late-onset SLE, defined as SLE diagnosed at or over the age of 50 years. These patients were compared with a group of 114 randomly selected patients aged younger than 50 years at SLE diagnosis. We compared clinical characteristics, laboratory data, therapy, and course. The female to male ratio was smaller in the late-onset SLE group (p = 0.0012). Some manifestations occurred less frequently in late-onset SLE: arthritis (p = 0.009), malar rash (p = 0.013), and nephropathy (p = 0.009). High-dose corticosteroids (p = 0.0016) and immunosuppressive drugs (p = 0.006) were less commonly used in the elderly. Deaths occurred more frequently in late-onset SLE (p = 0.019), with a 10-year survival rate of 71% versus 95% in early-onset SLE (p < 0.01). In patients with late-onset SLE, causes of death were usually unrelated to SLE. Analysis of pooled data from the literature, based on 714 old and 4700 young SLE patients, confirmed that late-onset SLE was characterized by a smaller female to male ratio (4.4:1 vs. 10.6:1; p = 3.10); a higher occurrence of serositis (36.7% vs. 28.6%; p = 7.10) and pulmonary involvement (21.2% vs. 11.3%; p = 6.10); and a lower occurrence of malar rash (31.1% vs. 62.4%; p = 10), photosensitivity (26.2% vs. 38.2%; p = 6.10), purpura/cutaneous vasculitis (13.4% vs. 25.9%; p = 9.10), alopecia/hair loss (24% vs. 44.9%; p = 3.10), Raynaud phenomenon (24.8% vs. 37.2%; p = 3.10), neuropsychiatric manifestations (15.3% vs. 20.2%; p = 0.025), lymphadenopathy (9.1% vs. 19.6%; p = 2.10), nephrotic syndrome (8.1% vs. 24.3%; p = 0.015), and nephritis (28.6% vs. 42.7%; p = 2.10). Regarding laboratory features, rheumatoid factor positivity was more frequent (32.7% vs. 20.1%; p = 3.10), whereas anti-RNP positivity (10.4% vs. 20.9%; p = 9.10), anti-Sm positivity (9.1% vs. 17.1%; p = 0.001), and a low CH50 complement fraction (45% vs. 64.9%; p = 0.002) were less frequent in old compared with young SLE patients. In conclusion, the clinical pattern of late-onset SLE is characterized by a lower disease severity. The reduced survival observed in this group seems to result mainly from the consequences of aging.
